Available variable types are:
.Pp
int -> hex rax2 10
hex -> int rax2 0xa
\-int -> hex rax2 \-77
\-hex -> int rax2 0xffffffb3
int -> bin rax2 b30
bin -> int rax2 1010d
float -> hex rax2 3.33f
hex -> float rax2 Fx40551ed8
oct -> hex rax2 35o
hex -> oct rax2 Ox12 (O is a letter)
bin -> hex rax2 1100011b
hex -> bin rax2 Bx63
.Pp
With no arguments, rax2 reads values from stdin. You can pass one or more values
as arguments.
.Pp
$ rax2 33 0x41 0101b
0x21
65
0x5

And it supports some math operations.
.Pp
$ rax2
0x5*101b+5
30
